LIGHIIN G FIXTURE.

Application filed February My invention relates to the lighting fixture art and has for its object to produce a unit adaptable for practically any type of installation in which the globe will be firmly seated and held in place by an adjustable and pivota-lly mounted carriage, the relationship of the parts and their construct-ion insuring a strong, durable, yet simple, lighting unit practically dust proof, and providing the simplest, and easiest conditions for general maintenance such as cleaning, relainping, replacing sockets, and the like.

A further object is to provide a carriage, or euirass for this purpose which will also function to draw the globe up against the globe holder thereby causing the holder and globe to form, in effect, a one piece, dust proof', unit.

A further object is to so construct the carriage, i or cuirass, that it will protect cracked globes and prevent them from falling, etc.

ll/Iy means of accomplishing the foregoing objects may be more readily understood by having reference to the accompanying drawings which are hereunto` annexed and are a part of this specification, in which:

Fig. 1 is a side elevation of my preferred form of embodiment of' my invention, part of the device being broken away to show the construction.

Fig. 2 is a top or plan view.

Similar reference numerals refer to similar parts throughout the entire description.

As shown in the drawings, the device comprises a one-piece globe 1 of translucent glass. This globe is secured to a holder 2 which is providedwith an upwardly extending central neck or stem 3 in which is mounted the standard socket 4 to which may be secured the usual electric light bulb 4. The top of the neck 3 is provided with an inwardly extending strap 5 in which is mounted the nipple 6 to which the socket is attached. This strap is secured to the neck adjacent a central-opening 7 which is provided with internal threads to which is fitted the external threads 8 cut on the supporting pipe 9 which may be secured to the junction or outlet box (not shown) inany convenient or desiredV manner. The lock nut 10 is provided to lock the pipe 9 securely to the holder. The holder 2 has a horizontal portion 11 which extends outwardly from the neck 3 and is provided with a downwardly depending peripheral flange 12.

10, 1925. Serial No. 8,100.

This flange has, at spaced intervals, a plurality of lugs 14, 15,and 16. The lugs 14 and 15 are biturcatedvfor a purpose which will .be hereinafter explained. The lug 1G is provided with a slot 17.- 'lhe inner surface 18 of the horizontal portion 11 of the holder 2 is highly polished forming a very excellent reflecting A surface.

The globe 1 secured .to the holder by means of a gasket formed, as shown, of two horizontal straps 19 and 2O and ayplurality of vertical straps 21, 22, 23, and24. As illustrated, these are four in number, but it will be apparent that any desired number may he employed sufficiently to support the globe.` At the upper end of the straps 21, 22, and 23, is mounted a bolt 26 which is* adapted to extend upwardly through the bifurcations of the lugs 14 and 15. Threads 27 are-cut on these bolts and wing nuts 28 are mounted thereon. The upper end 30 of the strap 24 is provided with a hook 31 which passes through the slot 17 and extends over and down beyond the end 32 of the lug 16.

As illustrated, the downwardly depending flange 12 of the holder is provided with an outwardly extending radial flange 33 which is ground to lit the curvature'of the globe 1 at its point of engagement therewith. A gasket 34 is mounted inside of the holder 11 and abuts the lip 35 of the globe l.

It will be apparent from the foregoing description that by tightening the wing nuts 28 upon the bolts 26, that the straps 21, 22, and 23 will be drawn upwardly bringing the lip 35 of the globe 1 tightly against the gasket, thus effectually preventing the entrance of dust, which operation is further facilitated by the curved portion of the flange 33 engaging the surface of the bowl.

Then it is necessary to clean or re-lamp the unit, it will be apparent from this description that by loosening the wing nuts 28,

the bolts 26 can be withdrawn from the hifureated lugs 14 and 15 and the globe will then swing downwardly, the hook 31 serving as a hinge so that it is possible for the workman to put the new lamp in, or to wipe out the bowl, or to replace the bowl in case off breakage, without having to come down from his ladder at all, thus greatly facilitating the work and materially reducing the cost of upkeep on the unit.

It will also be obvious to persons skilled in `the art, that by providing the cage or basket structure as I do, all danger of the globes Y.

falling by terially increasing the safety of the unit.

Although I have shown and described a specific form for utilizing my invention, it will be understood that I have done so only 'or the sake of illustrating a concrete embodiment of my invention, and l do not desire to be understood as limiting myself to the precise details of construction shown and described which" merely represent the prefered embodiment oi the invention.

Having described my invention, what I regard as new and desire to secure by Letters Patent of the United States is:

1. A lighting fixture comprising a globe holder with a substantially horizontal main portion and depending peripheral ilange on said portion; a globe to fit Within said globe holder; a carriage, which supports said globe when in both open and closed positions, comprised of metal straps, surrounding said globe; a hook to secure said metal carriage to the peripheral liange, one member of the reason of their being broken orl'ltjhook being on the flange and the other memcraeked, 1s completely eliminated thus ma- 1'; ber of the hook being on the carriage; ad-

" justable means for securing the metal earriage to the glope holder, substantially as shown and described.

2. A lighting lixture comprising' a globe holder with a substantially horizontal seetion and a peripheral flange depending therefrom; a. plurality of bifurcated lugs projecting from said peripheral flange; one member of a hook on said peripheral flange; a globe secured to said holder; a carriage comprised of a plurality of metal straps encircling the globe which supports said globe when in both open and closed positions, said carriage having upwardly projecting screwthreaded members to tit Within the slot in their respective bifurcated lugs, and a wing nut to travel onv each screw-threaded shaft: a mating hook secured to the carriage and adapted to mate with the hook member secured to the globe holder, substantially as shown and described.
